6 Claims. (Cl. 5-328) This invention relates to jacks and otherelevating devices particularly adapted for raising objects above a oorto facilitate moving the objects laterally, and in par ticular a jackfor elevating the foot of a bed with posts at the head of the bedpositioned in slots in iloor plates whereby with the foot elevated thelbed is free to be moved laterally away from a wall or from another bed,such as twin beds to facilitate making the bed and Without damaging arug or polished floor upon which legs or posts at the foot of the bedare positioned.

The purpose of this invention is to facilitate moving the foot of a bedlaterally away from a wall or from another bed to provide access to bothsides of the bed and to prevent damage to a rug or polished floor uponwhich the bed is positioned.

In numerous instances beds are positioned against a wall or twin bedsare positioned together and it is difficult to make the beds withoutmoving the foot laterally to provide space at the side of the bed. Withthis thought in mind this invention contemplates a jack having footpedal actuated cams with a ball in a bracket depending from the foot ofthe bed positioned in a rail carried by the cams whereby with one end ofthe rail elevated by one of the cams the bracket is free to slide towardthe `opposite end of the rail, and also floor plates having arcuatesl-ots therein in which posts at the head of the bed are positioned sothat as the foot is moved toward the side the posts at the head of thebed follow in the slots preventing posts or legs at the end of the bedbeing drawn over rugs, polished oors, and the like.

The object of this invention is, therefore, to provide means forelevating the foot of a bed to facilitate moving the bed laterally.

Another object of the invention is to provide a jack for elevating thefoot of a bed wherein the jack is provided with a rail upon which thebed is supported to facilitate sliding the bed with the posts at thefoot of the bed elevated above the floor.

Another important object of the invention is to provide elevating meansfor supporting an end of a bed above the floor as the bed is movedlaterally in which the device is adapted to be used on beds now in usewithout changing the design or construction of the bed.

A further 4object of the invention is to provide a jack for elevatingthe foot of a bed to facilitate moving the bed laterally in which thejack is of a simple and economical construction.

With these and other `objects and advantages in view the inventionembodies a bracket mounted on and depending from an end rail of a bed, ajack having a rail with the ends supported by'cams positioned on the oorand set whereby the lower end of the bracket travels in the rail, floorplates having arcuate slots therein in which lower ends of posts at thehead of the bed are positioned, and tie rods connecting the floor platesto the jack.

Other featuresand advantages of the invention will 2,862,213 PatentedDec. 2, 1958 appear from the following description taken in connectionwith the drawing, wherein:

Figure 1 is a perspective view of a bed showing the jack positionedbelow the foot and floor plates with arcuate slots therein positioned toreceive Iballs or casters on the lower ends of posts or legs at the headof the bed.

Figure 2 is a plan view of the jack assembly with the outline of a bedshown in the position for sleeping in full lines thereon and also withthe bed in the position in which the foot is moved laterally in brokenlines.

Figure 3 is a plan view of the bed elevating jack with the parts shownon an enlarged scale.

Figure 4 is a longitudinal section through the jack v taken on line 4-4of Fig. 3 showing one end of a rail of the jack in an elevated position.

Figure 5 is a cross section through one end of the jack taken on line5-5 of Fig. 4 also with the parts shown on an enlarged scale.

Figure 6 is a longitudinal section through the jack, with parts shown inelevation, said section being similar tot the section shown in Fig. 4except that the rail is in a horizontal position Referring now to thedrawing wherein like reference characters denote corresponding parts theimproved bed moving jack of this invention includes a rail 10, U-shapedin Cross section with the ends resting upon cams 11 and 12 andpositioned between uprights 13 and 14 at one end and 15 and 16 at theother end with the ends retained in arcuate slots 17 and 18 by pins 19and 20, respectively, a base 21 having an arcuate upwardly disposed ange22 and in which the uprights are mounted, treadles 23 and 24 foractuating the cams, oor plates 25 and 26 connected to the jack with tierods 27 and 28, respectively, and a bracket 29 having a ballor roller 30in a socket 31 of a threaded stud 32 extended downwardly therefrom, thebracket being designed to be `mounted on the lower sur# face of an endrail 33 of a bed, such kas the bed 34, with screws 35 orrbygother means.

The base or shoe 21 is formed with a smooth lower surface so that it isadapted to slide or move over a rug, polished iloor, lor the likewithout damaging the rug or marring the floor and the -uprights 13 vand14, at one end,and\whichlare integral with a base plate 36 are mountedin the base 21 such as by welding, and the uprights 15 and 16, at theopposite end, which are integral with a base plate 37 are secured in theopposite end, also, such as by welding, as shown at the points 38, andwith the cams 11 and 12 pivotally mounted in the uprights with shafts 39and 40, on the ends of which the treadles 23 and 24 are positioned, thecams are readily actuated by the treadles to elevate the ends of therail 10.

With the ball 30 of the bracket 29 riding on inner edges of llanges atthe sides of the U-shaped rail 10 the bracket is free to move laterallyand, as an illustration, with the bracket in the position shown in Fig.6 the cam 11 may be rotated to elevate the end of the rail whereby theball 30 will slide toward the opposite end, thereby making it possiblefor the housewife to move a bed from the position shown in full lines inFig. 2 to that shown in broken lines, Iby pressing downwardly on one ofthe treadles.

The cams are secured to the shafts, upon which they are mounted by pins41, as shown in Fig. 5 or by other suitable means. The rail 10 isretained in spaced relation to the uprights with spacing sleeves 42 andthe ends of the pins 19 and 20, which extend through the arcuate slots17 and 18, are provided with heads 43 and 44.

As illustrated in Figs. 4 and 6 the threaded upper end of the stud 32 isthreaded into hub 45 of the bracket 29, and the stud is provided with alock nut 46.

The iioor plates 25 and 26 are provided with tracks 47 and 48,respectively and the ends of the tracks are provided with depressions 49for receiving balls or rollers 50 of casters 51 on lower ends of legs orposts 52 at the head of the bed. l

The Hoor plates 25 and 26 lare connected to the jack with the tie rods27 and 28 and the plates are connected together with a rod 51.

With the posts at the head of the bed provided with rollers or castersand with the rollers or casters positioned in the slots or tracks 47 and48 the foot of the bed may be elevated and moved laterally, such as fromthe position indicated by the full lines 52 to the position indicated bythe broken lines 53 so that space may be provided between the side ofthe bed and a wall 5,4 or between twin beds, or the like.

It will be understood that'modications, within the scope of the appendedclaims, may be made in the design and arrangement of the parts withoutdeparting from the spirit of the invention.
